A Lifetime Of Work: The Lovelock Archive

It’s an amazing image to conjure with: the 23-year old James Lovelock, our most famous independent scientist, cradling a baby in his arms who would grow to become the world’s best known scientist, Stephen Hawking.

Lovelock told me about this touching encounter during one of his recent visits to the Science Museum, a vivid reminder of why the museum has spent £300,000 on his archive, an extraordinary collection of notebooks, manuscripts photographs and correspondence that reveals the remarkable extent of his research over a lifetime, from cryobiology and colds to Gaia and geoengineering.

Lovelock, who was born on 26 July 1919, must have encountered the great cosmologist in the year of Hawking’s birth, 1942, when he was working at the Medical Research Council’s National Institute for Medical Research, after graduating in chemistry from Manchester University the year before.

Hawking’s father was Frank Hawking (1905-1986) who spent much of his working life at the NIMR studying parasitology. Lovelock was doing research at the time of the encounter on sneezing and disinfection, publishing his first scientific paper, in the British Medical Journal, that same year.

As for his impact, there’s no better way to emphasise Lovelock’s stature than to read the foreword of one of his recent books, The Vanishing Face of Gaia, by Lord Rees, Astronomer Royal, and the Master of Trinity College, Cambridge, who describes him as among the most important independent scientists of the last century: “He is a hero to many scientists – certainly to me.”

Lovelock has made headlines for his views on the environment, and his support for nuclear power (he once told me he would happily store nuclear waste in his garden), but he is best known for introducing the world to the seductive idea of Gaia, which says the Earth behaves as though it were an organism. The concept first reached a wide audience in 1975 in an article published in New Scientist, but was ridiculed, attacked for being teleological, even mocked as an “evil religion”.

Lovelock’s computer simulation, Daisyworld, helped Gaia mature from a hypothesis into a theory by putting it on a mathematical foundation. Light, and dark, coloured daisies evolved within an idealised world, waxing and waning to balance the way they absorbed and reflected sunlight to regulate the temperature, so it was optimum for plant growth. Among the items acquired by the museum is a Hewlett Packard computer that Lovelock used for Daisyworld.

Bolstering Lovelock’s Gaian vision came experimental evidence, the discovery that sulphur from ocean algae circulated worldwide in a form that has since been linked with the formation of clouds that are able to cool the world by reflecting sunlight back into space. Today, Gaia’s influence stretches beyond Earth to music, fiction and even computer games.

The Science Museum’s collection includes Lovelock’s Electron Capture Detector which he invented in 1956 to detect a range of substances, he explained, ‘mostly nasty poisons and carcinogens, or else harmful to the atmosphere like nitrous oxide and halocarbons.’ In the summer of 1967 Lovelock used it measured the supposedly clean air blowing off the Atlantic onto Ireland’s west coast and found that it contained CFCs, now known to cause ozone depletion. ‘It’s sad that it would now be almost impossible for a lone scientist like me to make or use an ECD without breaking the health and safety laws,’ he told me.

I have met this green guru on and off since 1991 and, the last time we talked, he was as provocative as ever. The attempts to model the Earth’s climate system do not yet fully include the response of the ecosystem of the land or oceans, and Lovelock warned about feedback effects, some that can damp down climate change and others that accelerate it, and he predicts a threshold above which there could be a five degree increase in temperature.

He is withering about the attempt of the Intergovernmental Panel on Climate Change to forge a consensus, a word that he says has no place in science. That is no surprise. From 1964 Lovelock has worked as an independent scientist and he is writing a book about being a lone scientist in response to an article in the Wall Street Journal which argued that the scientific process can only happen through collaboration. Lovelock believes that lone scientists can work more like artists in that they can be reflective and do not necessarily need other people to collaborate with.

And when it comes to the fate of our home world, all is not lost. Lovelock, like many others, is receptive to another idea that, relatively recently, was laughed off as unrealistic, even a little mad: geoengineering, or “planetary medicine”, which could mean cooling the Earth by the use of space mirrors or clouds of particulates.

Lovelock, who has been visiting the Science Museum since the age of seven, teamed with a former Museum Director, Chris Rapley, to devise another way to cool our overheated world: pumping chilly waters from the ocean depths to fertilize the growth of carbon-hungry blooms.

In my view, Lovelock is the most important scientist since Darwin. The Ages of Gaia is essential reading and transforms our understanding of evolution and the link between life on all scales and habitat.

I agree that with Prof. Lovelock that unconventional approaches will be needed to addressing society’s human-induced problems. We need more out-of-the-box thinkers like Lovelock who do not shy away from controversy
